Definitions

  • blowing process in which a preform is in a Blow mold with the size and shape of the finished hollow body determining mold cavity or cavity introduced and in the closed form by introducing a pressure medium inflated into the preform, i.e. with its outer wall pressed against the wall of the cavity and thus molded there are three main procedural groups, namely the extrusion blow molding process, the injection blow molding process and the reheat process.
  • the invention is concerned with the reheat process, with the cartridge or sleeve-shaped preforms sprayed onto stock, taken from the stock when cooled and rotating around its axis through a heating section in which they are usually in several, from intercooling sections interrupted heating sections to the correct one Blow temperature to be warmed up again after leaving the heating section into a conventional blow mold to become.
  • the invention is directed to a preform loading station for reheat blow molding machines.
  • the preforms are placed on a conveyor, mostly chain, through the heating and intermediate cooling stations.
  • the preforms are attached to the chains Transport mandrels inserted with the mouth facing downwards, to the heat supplied, which is generally upwards rises from the cool, often threaded To protect the neck or mouth area.
  • the blow mold does not end at a reheat system a heating section or the preforms through the heating section leading transport organ, but the preforms from the heating section to a separate blowing section delivered, it may be appropriate and the Simplify delivery if the preforms are not continuous pass through the heating section, but through it be clocked through, with a clock, ie a transport phase and a standstill phase e.g. about 0.2 sec can be. Then the transfer from the heating section on the blowing section in a, albeit short, standstill phase between the bars.
  • a clock ie a transport phase and a standstill phase e.g. about 0.2 sec
  • preform loading station Several preforms are used - in the described and the example shown four preforms each - in a standstill phase of the heating section of this is given on a blow line. Such a facility is an example of the use of the preform loading station according to the invention.
  • a cylinder stop system 8 which during normal Operation basically in non-stopping position on the one hand, when production is stopped at the actual blowing system the further transport of preforms prevented, but especially in Start of the system ensured that the preform feed to turning wheel 7 to one based on the preform compartment 9 (Fig. 3) takes place at the exact time.
  • the turning wheel 7 is a compartment 9, e.g. twelve compartments for each preformed wheel, the compartments are limited by curved plates 9a, which are similar to plowshares are shaped such that their front edge 9a 'in Push a preform 1 into a compartment (Fig. 3B), while at the same time with its rear edge 9a '' inserting the following preform 1 'into the same Block the compartment and point it into the following compartment.
  • the drive system of the heating section chain 11 is the Reheat machine referred to that also the transfer of the heated Preforms on one or more blowing sections 19 controls.
  • the shaft 28 drives via a reduction 29, e.g. a Toothed belt or gear reduction, from in the case of execution 1: 2 the turning wheel rotating about a horizontal axis 13 7, while the shaft 27 one in the execution case 1: 1 toothed belt or gear ratio 30 drives, the one through a stepping gear 31 with the shaft ends 32 and 32 'drive shaft reaching on both sides works.
  • a reduction 29, e.g. a Toothed belt or gear reduction from in the case of execution 1: 2 the turning wheel rotating about a horizontal axis 13 7, while the shaft 27 one in the execution case 1: 1 toothed belt or gear ratio 30 drives, the one through a stepping gear 31 with the shaft ends 32 and 32 'drive shaft reaching on both sides works.
  • both Gear belt or gear reduction 29, the toothed belt or gear ratio 30 as well as the axle ends 32 and 32 'rotate continuously.
  • On the shaft end 32 ' is the press-on system described in detail later 16 mounted.
  • the stepping gear 31 is as a general well-known, commercially available globoid cam gear constructed such that a full revolution of the Axis 32, 32 'a 45 ° rotation of the working shaft 33 plus a standstill phase of curve-related time produced.
  • the stepping gear 31 is so in that System built in that the working shaft 33 vertically after shows below on which the crown wheel-like loading wheel 15 is applied, in the already mentioned clock division of 45 ° spring-loaded pairs of pliers 34 carries in the Are able to hold preforms non-positively.
  • the stepping gear 31 is with the drive system 17 of the heating section chain 11 of the reheat blow molding machine adjusts that whenever the chain 11, which is also the Transport mandrels 12 are in a standstill phase is located, the loading wheel 15 in a standstill phase stands, however, such that when the chain 11 to a new Clock starts, the clocking of the loading wheel 15 is delayed by so much is that those sitting on the mandrels 12 Preforms 1 from the spring-loaded pairs of pliers 34 can be released.
  • the stepper transmission has 31 a continuously rotating, through the gear through drive shaft 32,32 ', whereby on the side of the shaft 32 which e.g. Toothed belt ratio 30 acts while an eccentric on the side of the shaft 32 ' 36 sits with cam roller, over a backdrop 37 (FIG. 5) a carriage that can be pushed up and down vertically 38 drives.
  • a backdrop 37 FIG. 5
  • the sliding Carriage 38 with built-in backdrop 37 carries including of the eccentric disk attached to the shaft 32 ' 36 and a plunger attached to the slide 38 39.
  • the carriage 38 can, for example, due to the geometric Interpretation of the eccentric disc 36 and the backdrop 37, make a total stroke of 50 mm. While the heating track chain 11 with the built-up transport mandrels 12 and the loading wheel 15 is in a standstill phase, passes through the carriage 38, controlled by the eccentric disc 36 in connection with the backdrop 37, of its center of stroke from a vertical stroke of 25 mm to lower turning point and then again 25 mm from this Turning point towards the middle of the stroke upwards. This will be a preform 1 by one over the mandrel at this moment 12 standing, spring-loaded pair of pliers 34 through by means of the ram 39 attached to the slide 38 pressed on the transport mandrel 12.
  • the preform loading station is great for one high preform throughput such as more than 9000 Lay out pieces per hour. For this reason, the Unit fully automatic, i.e. without additional control elements from.
  • the preforms are with her Passage through the unit permanently under force, i.e. Kept control. Since the turning wheel continuously rotating, they are already oriented delivered preforms not a brake acceleration work subject.
  • the preforms are from Turning wheel inserted into the loading wheel under continuous force with practically no loss of fixation contact.
  • the charging wheel which clocks against it, takes over the preforms from the continuously rotating turning wheel in a precise rest position and releases the preforms in the rest position precisely to the heating section.
  • the preforms are targeted and precise on the mandrels belched the heating section.
